Sunnyside Limited was founded in Hong Kong in 1979. It initially made die-cast toy cars and its own manufactured products, and now offers over a hundred items under its brand.
Its employees' professionalism was first recognised in 1995 with an ‘A Grade Company Certificate’. In 1998 Sunnyside received ISO 9001 certification from the Hong Kong Quality Assurance Association.
Like most local manufacturers, it later moved production to Panyu, Guangdong, China. The premises cover 60,000 km², with four buildings housing the entire production process. A site for a new factory has already been identified for future expansion.
